METHOD AND APPARATUS FOR PROVIDING SELECTIVELY-COLORED LIGHT

摘要

An apparatus (10) for providing selectively-colored light is disclosed. The apparatus (10) includes a circuit having a plurality of diodes (DX) each including an anode and a cathode, wherein the plurality of diodes (DX) include a first diode (D1) that emits a first light having a first wavelength, a second diode (D2) that emits a second light having a second wavelength, and a third (D3) diode that emits a third light having a third wavelength, wherein a summation of one or more of the first, second and third light provides selectively-colored light; and a controller (12) including a first output (14) connected to the anode of the first diode (D1), and the cathode of the second diode (D2), a second output (14) connected to the cathode of the first diode (D1), the anode of the second diode (D2), and the anode of the third diode (D3), and a third output (18) connected to the cathode of the third diode (D3). A method is also disclosed.
